On 32-bit platforms, they're pretty dense. On IA64, quite a bit sparser, depending on the workload of course. I think that's mostly because of the larger pagesize on IA64 -- with 64k pages, you don't need very many to map a small object. I'm hoping IanW can give more details. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org. For more info on Linux MM, see: http://www.linux-mm.org/ .
